K cold start file-io items

[jhawk42]

@davidfowl here is the list of K cold start file io items

• Probe for the *.sha512 file over the network as well and that would not be found.
• Probe for *.nuspec over the network
• Probe for project.json files over the network
• Bunch of folder enumeration over the network
• Bunch of enumeration in the inner folder as well
• Contents of local files from d:\KCache are being read multiple times.
• File I/O Operations vs File I/O Bytes – graph - Notice that we spend a bunch of time (about 9 seconds) probing directory/file before we actually really start loading files
• File Summary – table - Something is doing a bunch of probing in \Program Files (x86)\Reference Assemblies\
